专家呼吁增进生态系统适应能力
生态系统 地貌
2017/2/14
一个国际专家小组在新一期《科学》杂志上发表报告指出，面对人口增长和气候变化，环保主义者应该利用新形成的生态系统，注重维护生态系统结构与功能的多样化，增进生态系统的适应能力，而不应总是试图让生态系统保持过去的状态。
清除入侵植物利于当地生物
入侵植物 当地生物
2017/2/14
清除入侵性物种可谓是一件永无休止的苦工，一些生态学家质疑是否值得付出这些努力。被人引入新生态系统的植物和动物往往会受到指责，因为它们会让本地动植物受到排挤，还会扰乱重要的交互作用，比如传粉。但科学家没有足够数据帮助他们判断清除入侵性植物是否会产生作用，并重塑健康的生态系统。

澳大利亚发现“仙女圈”（图）
仙女圈 生态系统
2016/3/16
几十年来，“仙女圈”难住了生态学家。被剥蚀土壤的圆形斑块散布在非洲南部干旱的草原上，并且拥有很多奇怪的特性。正如从空中所见，它们以类似于蜂窝的正六边形模式覆盖着当地的景观。圆圈中间没有植物，而边缘通常被很高的青草形成的矮墙包围，因此给人留下的印象是小仙女们建造的聚集地。
